buffer.Blob.constructor

Not implemented in Bun

constructor Blob(
sources: ArrayBuffer | Blob | BinaryLike[],
options?: BlobOptions
): Blob;

Creates a new Blob object containing a concatenation of the given sources.

{ArrayBuffer}, {TypedArray}, {DataView}, and {Buffer} sources are copied into the 'Blob' and can therefore be safely modified after the 'Blob' is created.

String sources are also copied into the Blob.

  • readonly byteLength: number

    Read-only. The length of the ArrayBuffer (in bytes).
